feat(resolvers): binky_rhythm_status query in state-hub resolver

Due-items for the three Binky operating-rhythm definitions
(BINKY-WP-0004-T02). Dueness derives from hub progress events recorded
by the executing session (binky_daily_brief / binky_mail_intake /
binky_weekly_review, detail.repo scoped); weekly_review carries
milestone_moved from event_type=milestone events in the last 7 days
(RISK-005 signal). Definitions' resolver comments updated; definitions
stay enabled:false until cutover (BINKY-WP-0004-T06).

7 new tests; resolver test file 31/31 green. Pre-existing failures in
test_railiance_ops_inventory_wiring/test_schedule_health are untouched.
